  • Upgraded from fc10 to fc12 now I have eth0_rename, how do I get back to plain old eth0?

    - by shank
    I upgraded from Fedora 10 to Fedora 12. Unfortunately, my ethernet interface eth0 is now named eth0_rename. I'd like to get back to having it named plain old eth0. I googled a bit but the solution of removing the eth0 entry from /etc/udev/rules.d/70-persistent-net.rules seems to have no effect (I restarted the network service but didn't reboot). The interface works just fine although I could see a script or two having a problem with the format. So, it's more of an inconvenience thing than anything else. Any ideas? Thanks.

  • How to upgrade XMBC Live from 9.04.1 to 9.11?

    - by sunpech
    I've been unable to do a fresh install of XBMC Live 9.11 to my hard drive. Everytime it fails at the Install System step. But I am able to get XBMC Live 9.04.1 to install successfully. How do I upgrade XBMC Live 9.04.1 to 9.11? I understand that Ctrl+Shift+F2 brings up the command line, but what are the next set of commands to run?

  • Using WinSCP with SSH server and 2 machine hops

    - by Mike
    I'm on a windows machine using putty to ssh into my schools server. From there I need to "slogin -XY machine1" and then "slogin -XY machine2" . Ideally, I'd like to use WinSCP to connect and transfer files. I know I can do this by using two copies of PuTTY , one to ssh into the server and create a proxy, and the second PuTTY to connect to the proxy and login to machine1 and create a second proxy. I can then use winSCP to connect to the proxy server and login to machine2... Is there a simpler way of doing this?

  • Which mail clients can give reminders about unresponded emails?

    - by ulidtko
    In my daily e-mail often happens the following scenario: I send somebody an email which describes some problem and requests an action from the recipient. Typically, I wish to ensure that this action was taken, or at least somehow resolved; when this happens, the email recipient should notify me with a response email about what was done, and what was not and why. But, sometimes emails don't get read by the recipient, or he forgets to reply to me. At the same time, I cannot constantly keep in memory the list of all emails for which I was waiting an answer and still didn't receive it. So I wonder, is there in any email client such a feature which would allow me to somehow mark specific outgoing emails as "demanding reply"? The mail client could in this case notify me if any "demanding reply" emails still aren't replied for a long time.

  • sudo midnight commander

    - by mit
    I sometimes start midnight commander as superuser with the command sudo mc to do some operations on the current working directory as superuser. But this results in ~/.mc having the wrong permissions, which I need to fix manually. Any solution? Edit: I accepted an answer. I want to further add, that .mc is a directory, so my solution goes like this: $ cd ~ ~$ sudo chown -R mit.mit .mc ~$ chmod 775 .mc ~$ cd .mc ~$ chmod -R 664 .mc ~/.mc$ chmod 775 cedit It seems not to be a good idea after installing mc to use sudo on its first start .

  • Recover LVM2 volume group after one HDD failed

    - by Bernd
    I had two HDDs, each one containing a LVM partition which formed a volume group. Then I had two LVs, one for my / directory and one for my /home/ directory. Yesterday where I had my / dir failed. I'm trying to recover at least my /home/ dir. What I've done so far: Boot a live system Extract LVM2 metadata from the working HDD using dd Copy metadata to /etc/lvm/backup/vg0 Now I'm trying to do this: pvcreate --restore /etc/lvm/backup/vg0 --uuid "[uuid of my working hdd]" /dev/sdb2 But I always get: Couldn't find device with uuid '[uuid of broken hdd]'. Couldn't find device with uuid '[uuid of working hdd]'. Device /dev/sdb2 not found (or ignored by filtering). I confirmed that /dev/sdb2 exists and I've commented out all filtering settings from /etc/lvm/lvm.conf so I don't know what might be causing pvcreate not to find the device. So: What might be the problem? Is it even possible to restore this partition? (As I'm writing this I'm starting to think it's impossible D:) Edit: Okay, looks like I've got it figured out. I was using a Ubuntu 8.10 CD (yeah, I know it's not supported anymore) and it seems that was the problem. When I started from a Ubuntu 10.04 CD everything worked 'fine', I could mount my LVM partitions partially without problems. (Will answer the question in 4 hours. But if anyone has still got some hints/tips, please share! :)

  • GNU screen - Unable to reattach to screen after lost connection

    - by subhashish
    I was using irssi in screen but lost connection. After I ssh'd back in to the server, I can no longer attach to that screen. screen -ls shows that the screen is already attached. I tried screen -D to force detach it, and it said detach but screen -ls still says it's attached. I tried screen -x and it just hangs there. [sub@server ~]$ screen -ls There are screens on: 4033.poe (Detached) 7728.irssi (Attached) 2 Sockets in /var/run/screen/S-sub. What can I do now?

  • xinet vs iptables for port forwarding performance

    - by jamie.mccrindle
    I have a requirement to run a Java based web server on port 80. The options are: Web proxy (apache, nginx etc.) xinet iptables setuid The baseline would be running the app using setuid but I'd prefer not to for security reasons. Apache is too slow and nginx doesn't support keep-alives so new connections are made for every proxied request. xinet is easy to set up but creates a new process for every request which I've seen cause problems in a high performance environment. The last option is port forwarding with iptables but I have no experience of how fast it is. Of course, the ideal solution would be to do this on a dedicated hardware firewall / load balancer but that's not an option at present.

  • How to convert aspell dictionary to simple list of words?

    - by rafalmag
    I want to get list of all words from aspell dictionary. I downloaded aspell and aspell polish dictionary, then unziped it using: preunzip pl.cwl I got pl.wl: ... hippie hippies hippiesowski/bXxYc hippika/MNn hippis/NOqsT hippisiara/MnN hippiska/mMN hippisowski/bXxYc ... but they appear with sufix like /bXxYc or /MNn. These suffixes are defined in pl_affix.dat, which looks like ... SFX n Y 5 SFX n a 0 [^ij]a SFX n ja yj [^aeijoóuy]ja SFX n a 0 [aeijoóuy]ja SFX n ia ij [^drt]ia SFX n ia yj [drt]ia ... It is connected to the declination and conjugation. How can I add to the first list all forms (with all corresponding suffixes as defined in .dat file ) ? BTW: I need this list to spell-checker jazzy.

  • How do you manage perl modules on a Debian system?

    - by nagul
    I'd like to know if you have a method for managing perl modules on your Debian system, with respect to the following: Installing new modules Listing of manually installed modules Checking dependencies, and uninstalling modules I have looked at this perlmonks article for background reading: What is the best way to install CPAN modules on Debian? I have previously installed perl modules using the CPAN module. I have also used dh-make-perl in some cases, when following instructions to build other packages that had perl dependencies. I'd like to institute a coherent policy on my machine so I can better manage how and where the modules are installed, and reduce the chance of breaking perl on my system. I would strongly like a system where I can detect and uninstall modules that are no longer being used.

  • Why should krfb use so much cpu when I never use it?

    - by Newton Falls
    I was playing around with KSysGuard and I noticed the process using the most cpu was krfb, which is the server process for desktop sharing. I never use desktop sharing so I suppose it is a default loaded process. Why would this process use so much juice (around 15%) when I never use it and it really shouldn't be doing much of anything? I don't see any network activity so I don't think I am being hacked. I have suspended the process and nothing bad seems to have happened. Can I assume this is a safe thing to do?

  • Look strange on gvim after applying Source Sans Pro font

    - by abcdabcd987
    I downloaded the Source Sans Pro font and install on my Fedora17(Xfce). I did mkfontscale, mkfontdir, fc-cache -fv, and after fc-list, could see it on the list. Then I changed guifont in gvim to Source\ Sans\ Pro\ 10, but it looks quite strange. And then I changed it to DejaVu\ Sans\ Mono\ 10, it looks nothing strange. So, why would this happend? And how to solve it? Thanks! Source Sans Pro DejaVu Sans Mono

  • Why isn't "(ulimit -d 1000; firefox) &" working?

    - by MaxB
    I'm trying to limit the memory usage of firefox to prevent it from stalling the whole system with problematic web sites. I tried, in bash: (ulimit -d 1000; firefox) & This should limit the memory usage to 1000kB. Then I opened YouTube, and noticed, in top, that firefox is using 2.6% of the memory, or about 200MB, and not crashing. Clearly the limit is being ignored. Why is that, and how can I enforce it correctly?
